Hello Rahul,

    I think you will understand with this example so look at the code
            $var = 'hello';
             $$var = 'word';
            echo $hello;
     For example, the code creates a variable called $hello and outputs the string 'world'.  The double dollar sign     declares that the value of $var should be used as the name of newly defined variable.

Hope this will help you....!!!!!
